Filtering is just pulling the paint out of the air not the VOC's. Not realistic in a "home built" scenario. If you are worried about the neighbors smelling it, you could paint at night when they are likely to be inside.

To many bugs ...The absolute best time is daybreak,when the dew is on the ground and holding all the dirt in place and everybody is asleep..just make sure everything is ready so all you have to do is turn on the compressor and pull the trigger...
having furness filters on the exhust side can help a little with the smell if you wet them down.
